Pectin-II, isolated from the fruit rind of Citrus unshiu MARCOVITCH, was hydrolyzed with an acid, oligogalacturonic acid thereby formed was oxidized with sodium periodate, and a hydrazone of its oxidation product was obtained by reaction with phenylhydrazine or isonicotinoylhydrazine. Reduction of this oxidation product with sodium borohydride and hydrolysis of the reduction product with hydrochloric acid afforded glycolic aldehyde, L-glyceric acid, and D-threonic acid. A structure was proposed for the oligogalacturonic acid from these derivatives and decomposition product.
